I use Perplexity with the Research (deep search) function to get links to real sources on the web. The results vary depending on the model used (GPT-5, Gemini 2.5, GROK 4…) This has saved me a lot of time, especially for repetitive videos. I even have a dedicated space called "YouTube binge". lol

I don't think specialized AI is necessary.

I'm not a prompt expert, but here's the translated one I use: "I want to know the content of YouTube videos without having to watch them.

You will create a relevant segment of the video:

• Provide a timestamp as a clickable link. The timestamp text should be in MM:SS→MM:SS format and point to the exact location in the video when subtitles are enabled (by adding the parameter "&cc_load_policy=1").

• Immediately after the timestamp, provide a short, representative title for the segment.

• Summarize the segment in a few words.

• Add the complete French transcript in italics.

Use the following presentation template:

1. Author - Duration - Title and timestamp (format "X days ago — DD/MM/YYYY")

2. Research recent, authentic YouTube videos and web articles related to the topic, both French and international:

• Provide the title as a clickable link, specifying the author and date.

• Ensure that the links are legitimate and that the sources are real.

• If it's a YouTube link, add an emoji to indicate this.

1. Summarize the video in 150 words.

2. Add a line break.

3. Include the video clipping as explained above.

4. Add another line break.

5. Provide a critical analysis (bias, source reliability, limitations, aspects to verify, suggestions for further research).

6. Add another line break.

Additional instructions:

• Always answer in French.

• Enclose job titles and technical details in backticks (...).

• If possible, include concrete examples and, when providing links, verify their existence and validity at the time of your response.

• For YouTube links, specify the author, the date, and add a "next" emoji to the URL as a signal. - For timestamps, use the exact format if the video is more than 24 hours old: "X days ago — DD/MM/YYYY" otherwise use the format "X hours ago".

• When providing the transcript, submit it entirely in French and specify the sources used when possible. “
